Bearing forging

Forging processing is the primary processing of bearing ring processing, also known as blank processing.
The main purpose of ring forging is:
1 To obtain a blank similar to the shape of the product, thereby improving the utilization rate of metal materials and saving
Raw materials, reduce the amount of machining, reduce costs.
2 Eliminate the inherent defects of the metal, improve the metal structure, and make the metal streamline distribution reasonable
The tightness is good, thus improving the service life of the bearing.
Process forging Cold forging - Metal deformation at room temperature Hot forging - Metal heating above recrystallization temperature Warm forging - Metal deformation between hot and cold forging is used in large quantities and rarely in the experimental stage
